I would recommend you try using DevStack ( http://wiki.openstack.org/XenServer/DevStack (http://wiki.openstack.org/XenServer/D...) ).

I have not seen that error myself, but it looks a lot like a configuration issue.

If you could check the api-server and the scheduler logs they may be able to give you some hints as to why it thinks you have reached your quota. Maybe the way you integrated keystone is not quite working?

It might be worth checking the clocks to ensure it does not simply think there are no resources avaiable (but I thought that would give you a different error).
